One engineer, many orbits.

I’m a senior software engineer with more than fifteen years of experience, mostly in .NET full-stack development, with deep work in cloud and AI.

I began my career in India in 2010 and have worked across Mumbai, Gandhinagar, Hyderabad and Bengaluru. I studied in Pondicherry. I also spent five years working internationally in the USA, and from the start I’ve worked for global clients and with people from many backgrounds. That shaped how I think, communicate and build.

Outside my day job I build and ship my own products. Some are apps on the App Store, some are tools for clinics and small businesses, and some are platforms for sport and community. I like owning a problem from the first sketch to the support inbox.

I’m tech savvy and always scouting for new products, from the tools I build with to the everyday products I use in my personal life. I don’t settle for what simply exists in the market: I choose what matches my vision and the way I want to live and work.

I don’t stick to one tech stack. My vision and experience shape how a product is designed and built, and the technology follows.

I wanted to do an MBA at a global business school, but circumstances didn’t allow it. So I’ve been learning business the hands-on way instead: talking to potential customers and partners, working out how to reach and capture a market, evaluating revenue models from affiliate links to paid plans, and finding out first-hand how hard it is to win traction. I’m still learning, and I enjoy it.

I’m now looking to grow into new fields and do my best work there, and I bring a founder’s habit of learning fast and shipping.

What makes me happiest is success I can share: building something that works and giving back to the community around me. Away from the screen, I play badminton regularly, keep up with the latest in tech, and unwind with movies and music. Next on my list is reading more great books.

On-device firstIf a phone can do the job privately, I keep it there. Fewer servers means lower cost and better privacy.
Write the decisions downMy healthtech platform has twelve architecture decision records behind a deterministic rules engine.
Ship, then listenI launch early, handle real feedback, and rework what doesn’t hold up.
Fit the vision, not the shelfI scout new products, from work tools to the things I use every day, and pick what matches my vision instead of settling for whatever already exists.
Disciplined and law-abidingI manage money carefully, keep running costs low, and follow the law and the rules in everything I build and run.

Never give up. Rise again.

“Aim for the stars. You might end up on the moon.”

I’m inspired by anything done at its best. The world is shaped by people who keep learning and refuse to give up, and that’s who I want to be.

I stay positive and aim high. I’ve faced setbacks in work and in life, and each one has made me stronger and more focused. When something doesn’t work out, I learn from it, get back up and keep building. Every experience and failure has made me faster, and today I can build any product quickly once I connect with its vision. Even a sudden move from the USA to India didn’t hold me back.

Experience

A long career in production software, with a second track of products I build myself.

  1. Now

    Indie product builder

    I design, build and launch iOS and web products on my own. Right now I’m actively working on ShuttleScience, while keeping my other ventures moving.

  2. Day job

    Senior Software Engineer, Miracle Software Systems

    Full-stack engineering in .NET, with cloud and AI work, and strong troubleshooting across production support, development and maintenance. For Sherwin-Williams, I worked on Mosaic GMSColor, a color management web app for paint formulation, using React, ASP.NET Core and Azure Functions, along with Azure AD sign-in, TDD and CI/CD pipelines that cut manual release effort by over 60%. I work remotely from Tirupati. I’m currently on unpaid leave, and I’ve requested a sabbatical so I can focus fully on ShuttleScience.

  3. 2021 – 2024

    Banking, security and energy platforms for US clients

    At Truist Financial, I worked on Azure microservices for Golden Gate, a platform for supplier and customer invoicing. At Morgan Stanley, I moved legacy WebForms security apps to Angular and .NET 6 and brought in Snyk and Fortify to fix vulnerable dependencies. At Landis+Gyr, I worked on the App Manager platform for smart meters and its migration to .NET 6. At Microsoft, I worked on Partner Center with Azure Functions and Cosmos DB.

  4. 2019 – 2020

    Corporate finance systems, Meijer

    I worked on .NET finance and reporting systems for sales analytics, tax and audit, and owned TLS compliance fixes across more than 50 applications.

  5. 2014 – 2019

    Tax, records and integration platforms, Deloitte

    I worked on Deloitte’s Firm Tax platform with Angular and Web API, and on its daily data integration from SAP. I also worked on a fault-tolerant sync from SAP to Sitefinity for a life-sciences company, and gave L3 production support for Deloitte’s records management system.

  6. 2010 – 2014

    Banking and education systems, iGate

    For Royal Bank of Canada, I led work on investment banking apps: FATCA compliance, mutual SSL for mid-tier APIs and a .NET framework migration. Before that, I worked on Progresso, an education management system for Serco UK.

  7. Abroad

    5 years of international experience in the USA

    I worked for global clients and with diverse people, and that experience shaped how I work with teams, customers and ideas.

  8. Since 2010

    A career that began in India in 2010

    I studied in Pondicherry, then built my career across Mumbai, Gandhinagar, Hyderabad and Bengaluru. The discipline of production systems shows up in my side projects: written architecture decisions, deterministic logic where it matters, and low running costs.

How I build, with AI as a force multiplier.

I own the product vision, architecture, technical decisions and implementation of what I build. I use AI tools to move faster, explore unfamiliar technologies and turn ideas into working software, and I stay responsible for the product’s direction, design decisions and quality.

I’m transparent about using AI as a development tool. I see it as a force multiplier for my ability to execute.

I own the directionVision, architecture, technical decisions and quality stay with me.
AI speeds me upIt helps me build faster, learn unfamiliar technologies and turn ideas into working software.
My stack doesn’t limit meMy background is .NET engineering, but I don’t let it limit what I can build.
Built to scale globallyWhat drives me is the product vision and the ambition to build something that can scale globally.

Projects

What I’m building now, what I’ve shipped, and what each project taught me, including the setbacks. Together they help me build any product quickly once I connect with its vision.

Actively building now

ShuttleScience

A digital platform for the badminton community.

  • Web app
  • Netlify
  • Community

shuttlescience.com

  • ShuttleScience Labs is building a digital platform for the badminton community, bringing players, venues and the wider sport closer together.
  • This is my main focus right now. It began when my son wanted to learn badminton and I couldn’t find good free resources, and it started as a free training site.
  • Training guides, parent-managed child accounts, and short videos on Instagram, YouTube and Facebook.
  • My biggest challenge across my projects has been winning market share and user traction, not building the product. That’s exactly what I’m working on now with ShuttleScience. I’ve already spoken with several badminton venue owners at the venues where I play and kept them well informed about this futuristic badminton platform.

There’s a bigger vision behind it, and I’m happy to walk you through it in person.

Shipped on iOS

WanderFree

A driving safety app that runs entirely on your iPhone.

  • Swift
  • ARKit
  • CloudKit
  • Netlify

wanderfree.app

  • Detects driver drowsiness, records with both cameras for Dash Alert, and sends an SOS in one tap.
  • No server backend: the safety features work on the device itself.
  • Launched on Product Hunt after working through App Store review, in-app purchase setup and TrueDepth camera disclosure.
  • Runs a live status page powered by CloudKit and hosted on Netlify.
Taken down

ReportEasy and the healthtech platform

From an AI medical report explainer to modular clinical software.

  • Gemini API
  • Flask
  • React Native
  • PostgreSQL

reporteasy.in (taken down)

  • ReportEasy turns medical reports into clear summaries in local languages, suggests what to ask your doctor, and keeps track of the numbers in your reports over time.
  • It was built on Firebase and the Gemini API, with an integrated payment gateway.
  • I had to take reporteasy.in down after some of its API credits were misused. The idea lives on in the healthtech platform.
  • It has grown into a modular platform with a deterministic clinical rules engine, documented in twelve architecture decision records.
  • A planned LLM presentation layer will sit on top of that engine.
Taken back

Cardmate.me

A single platform to compare credit cards and get suggestions on which one fits you. When someone applied through my site, I earned affiliate revenue. I built it using Lovable, the AI app builder.

Taken back

LocalBestie

Built to help solve the many WhatsApp and Facebook group conversations that happen in every city across the NRI community in the USA. A venture set up in my wife’s name. I took it back after a sudden move from the USA to India because of visa circumstances, and it didn’t hold me back.

Built for a friend

Punarv Health

The marketing website for my friend’s transitional care center in Kokapet, Hyderabad, plus the staff web app behind it: roles, face-based time tracking, payroll, appointments and WhatsApp reminders.

punarvhealth.com

Taken back from the App Store

Lulra

Apple Watch sleep app with an adaptive heart-rate-variability and movement algorithm, refined over four nights of live testing. I took it back because I wasn’t satisfied with the results, and I kept the lessons.

lulra.app

Played around and skipped

What’s next: ideas that can change the world.

I have more projects in mind that use technology to make a real difference in how people live, stay healthy, move and learn. I’ve proven I can build and ship on my own. Now I want to build them at a bigger scale.

All I’m looking for is the right launchpad to start from, and the right tools to take these ideas as far as they can go.

Start a conversation

The right launchpad

A program, team or partner that helps me start well and grow fast.

The right tools

The technology, resources and support that let me build big ideas properly.

The right people

Founders, mentors and teams who want to build something that matters.

Looking for a cofounder?

I’m building towards an AI-native company that uses agentic workflows to run with a lean, highly productive team. I’m even exploring what a one-person unicorn could look like.

I’m open to a cofounder who shares that ambition, is as passionate about the problem as I am, complements my strengths, and shares my approach to building and scaling a global product. I value genuine alignment, trust and execution over simply adding another person to the team.

Talk to me

Let’s build something useful.

I’m open to conversations about AI product engineering and senior engineering roles, product ideas and collaborations.
